Flow Rate: Refers to maximum recommended Gallons Per Minute ("GPM") which means how fast the water is flowing. The 1.5 CF model works best for most homes (such as 2 -3 bathroom homes with 2 - 6 persons). However for homes with 2 - 4 persons, the 0.75 or 1.0 CF models work great. Higher flow rates are possible through these systems, this is just meant as a guide or suggested use.

Iron levels over 5 PPM, or when manganese or other conditions such low pH, high levels of sulfur odor or iron bacteria or tannins, please note that additional treatment such as chlorine, peroxide, or aeration may be needed.

Manganese removal: when manganese is present, we recommend a chlorine feed. A chlorine feed with a contact/retention tank allowing 30 seconds of time after the chlorine has been injected, followed by the Pro-OX filter systems does a GREAT job on removing manganese. A carbon filter can be used after the Pro-OX system to remove any residual chlorine, so you get all the benefits of chlorination without having any chlorine in the house water.

Hydrogen Sulfide Rotten Egg: if hydrogen sulfide is present and the water also contains iron, we recommend an Air-Charger Pro-OX system. If the hydrogen sulfide levels are over 5 PPM, we recommend a chlorine feed, and/or aeration prior to the Pro-OX system. Please contact us for more information if you need assistance.

Pro-OX Filters are the longest lasting and most powerful system for removing iron, rust and sediment from well water.

Contains a unique blend of high-purity manganese dioxide (Pro-OX) and naturally mined Zeolite for filtration down to 3 microns for maximum filtration and iron removal.

System automatically backwashes based on days (time clock version) OR with the optional Backwash On-Demand Flow Sensor. Reliable heavy-duty 5900e control valve is easier to program than other valves and features an optional built-in flow sensor that tracks water usage and backwashes iron filter based on gallons used, and/or by days of the week!

Backwash Flow Rate and Quantity: uses 50 - 100 gallons of backwash water 1 to 3 times a week depending on water use. Compared to other iron filters, the Pro-OX filter uses 50% less! Safe for septic tanks.

Pro-OX Manganese Dioxide is an NSF Certified natural high purity mineral that is used for removing iron, hydrogen sulfide, and manganese from water supplies. Removes up to 30 PPM iron and 15 PPM manganese. Higher levels possible with injecting air, chlorine or hydrogen peroxide ahead of filter. Iron bacteria, hydrogen sulfide and tannins can also be removed, contact us for more details.

Pro-OX media utilizes an oxidation-reduction reaction and filtration process similar to Greensand, but at a much higher level of performance. It works much better than other solid manganese dioxide iron-filter media due to its higher purity and porosity.

Pro-OX Manganese Dioxide generally works better than Greensand or Birm, due to its high purity, superior oxidation/filtration ability. Unlike coated iron filter media such as Greensand or Birm or MTM, Pro-OX lasts for many years and doesn't have a coating to wear off or deteriorate like other iron filter media.

Note that in some waters aeration, hydrogen peroxide injection or chlorination is used before the iron filter to increase removal rates of iron, manganese and hydrogen sulfide.

Filter tank is NSF certified one piece seamless polyester construction for long life.

Use Less Backwash Water and Get Much Longer Life With the Pro-OX Iron Filter!

For over 25 years our well water iron filter systems have been successfully removing iron, iron bacteria, manganese and hydrogen sulfide ("rotten-egg sulfur odor") throughout the U.S. and Canada, and in over 50 countries world wide.

Pro-OX Iron Filters last longer, and are more effective at iron removal than other systems using coated filter media. Other media such as Katalox, Birm, Greensand or MTM all require some type of air injection, air oxidation or chemical feed ahead of the iron filter. For example, a typical air-charger system using Birm, MTM, or Katalox light, requires regeneration every 1 - 2 nights to replenish the air inside the tank. These sysems use a lot of water for backwash.

Our Pro-OX systems use a particularly high grade of natural manganese dioxide. The media is carefully selected from large quantities of ore to get the highest purity, most porous manganese dioxide mineral. The media is more porous and has a higher reactivity for oxidizing iron, compared to other similar media. Unlike other iron filters, such as air-charging systems that require a nightly backwash, our systems do not need backwashing everyday.

How Do Pro-OX Iron Filters Work?

Pro-OX Iron filters oxidize (turn to rust) dissolved ferrous iron in water to an insoluble particle and trap the iron (now "rust") in the iron filter media.

A periodic short rapid backwash cleans out the rust and flushes the filter media clean.

Frequently Asked Questions About Iron Filters

Q. How do Pro-OX iron filters actually remove iron?

A. Pro-OX iron filters work by oxidizing (rusting) the iron and then filtering it out. We all know that simple iron or steel will rust in the presence of air and water. Rust is one type of oxidation. When water is underground in most wells, it is often clear. This is known as 'ferrous' or clear water iron. Iron filters take this clear iron and transform it to rust or ferric iron in the process known as oxidation. These trapped particles are periodically and automatically backwashed out to drain, usually once or twice a week. Iron filter systems also remove so-called red or red‐water iron, iron bacteria, manganese and in some cases hydrogen sulfide by oxidation and filtration.

Q. What is the difference between Pro-OX, Birm and Greensand iron filter filters?

A. All of these filters use a manganese-dioxide filter media, but media such Birm, Katalox and Greensand are manufactured with a thin coating of manganese dioxide over a core of some other cheaper filter media. Manganese-Dioxide is a powerful oxidizing filter media and is highly effective for filtering iron and manganese from water. The higher the concentration of the manganese dioxide, and the more porous the manganese dioxide media is, the faster it works in removing iron and manganese.

Pro-OX manganese dioxide is over 85% manganese dioxide, compared to 10% or less for the other less expensive filter media. The result is far superior performance with higher flow rates in smaller filter vessels, compared to other types.

With the coated manufactured types of iron filter media, the coating eventually wears off and breaks down. With Pro-OX media there is no coating to wear off and the media lasts much longer, up to 20 years typically.

Q. Don't the Pro-OX type iron filters waste a lot of water compared to the Birm type filters?

A. No. The Pro-OX filters remove a higher amount of iron before requiring backwash, so they do not use significantly higher amounts of water over-all. In fact, compared to air-charging types, which suck in a head of air each night during backwash and run water for 45 minutes to an hour, the Pro-OX filter use much less water.

Q. Can't I just use a water softener?

A. Water softeners will remove dissolved clear water iron by a process known as ion-exchange. However, iron, manganese and/or hydrogen sulfide gas can eventually foul and ruin the ion-exchange resin. If your water contains less than 2.0 ppm of iron and manganese combined, and no sulfur odor, then you may be able to use a good quality water softener with fine mesh resin and a special type of resin cleaner in the brine tank. The resin cleaner will help clean the resin when the softener is being regenerated with the salt water. We don't recommend this approach however, its better to use an iron filter in front of the water softener for best results.

Q. I don't want to use chlorine or any chemicals of any kind. My water has sulfur odor, a LOT of iron, and manganese as well. What system should I use?

A. The best approach is to use our air-compressor air injection system with the Pro-OX filter. This is not only non-chemical, it is also virtually maintenance free and requires no regular or routine maintenance.

Q. I use a chlorinator already to control odor and disinfect the water, but I want to use an iron filter. Which one is best?

A. The Pro-OX iron fitlers works the best, and no potassium permanganate or other chemicals are required.

Q. I have very severe water. i have very high iron, high manganese, and a terrible hydrogen sulfide "rotten-egg' sulfur
problem. I suspect iron bacteria, because our toilet flush tanks are very slimy. Which one should I use?

A. For some types of very severe water, we recommend injection of chlorine or hydrogen peroxide, depending on the water chemistry, followed by a contact retention tank, then a Pro-OX iron filter, and in some cases an additional carbon backwash filter. This approaach can handle very high levels of odor, iron and manganese. Contact us for a fast quotation for this type of system.

Q. I would like to use the Pro-OX iron filter, with a chlorine injection system, but I don't want chlorine in my house. What can I do?

A. The chlorine can be adjusted so it degrades as it flows through the iron filter, so you don't have the taste or smell of chlorine in the water. You can also use a backwashing carbon filter or a large carbon cartridge after the Pro-OX or Greensand filter to remove all trace of chlorine before it enters the house.

Q. What does 'backwash flow rate" refer to?

A. All iron filters require a certain amount of water flow to able to backwash and clean the iron filter media periodically. For example if your well pump can fill a 5 gallon bucket in 60 seconds, then you well pump can pump 5 gallons per minute, or 5 GPM. If your well can fill the 5 gallon bucket in 30 seconds, then you have 10 GPM. Most residential wells can pump 10 to 20 GPM but it is important to verify it before selecting your iron filter. If you have low flow rate of say 5 GPM and you select an iron filter that requires 10 GPM, then the iron filter will become fouled over time.

Q. How can I find out how many gallons per minute my well pump can produce?

The iron filter system is working very well.We're very happy with the system, and really appreciate your help.

Clean Water,

Very happy with the system. Customer support and recommendations were exceptional. With the installation of the 'Twist II Clean' sediment filter there is no longer a need to replace a filter monthly. Decided to replace everything, so I spent lot of time planning for this installation so that it would be mostly maintenance free. Fairly easy install with the information provided and the resources that are found within the website. This finishes phase one. Phase two will be installing a homerun PEX system.

10 year Warranty on the filter tanks. All tanks are NSF Certified & top quality.

7 Year Warranty on the control valve. Made in the U.S.A.

90 Day money-back guarantee!
